The operands of these bitwise instructions could have different types and still be valid Wasm (i.e. `v128`). Because of this, we must tell Cranelift to cast both operands to the same type--the default type, in this case. This undoes the work merged in https://github.com/bytecodealliance/cranelift/pull/1233.
This crate performs the translation from a wasm module in binary format to the in-memory form of the Cranelift IR.
If you're looking for a complete WebAssembly implementation that uses this library, see Wasmtime.
